* In many places,
machines create paper ballots just for people with disabilities, who cannot
mark their own.

** Paper roll is shown
under a window, so any voter can check her votes are printed on paper
correctly, but it is hard to count.

Voting
jurisdictions can be counties, towns, etc., depending on state law. Many appear
in multiple columns, for example if they have machines to help people with
disabilities, they are also in a column to hand-count or scan ballots, and may
have other machines to scan mail-in ballots. Alaska has the same system
state-wide, and appears once.
